I like the idea of figure 4 of your "concepts"-website. I'm just not sure how that would be implemented in practice. Food for thought.

that's not my website, but several of my posts/sims here at diyaudio show the impedance network used to separate the 2 amps by by frequency - the "coarse" amp is low pass connected to the load, the fist "corrrection" amplifier is high pass connected by the different L, R impedances Z3,4

sorry the earlier search must have given a dynamic link or otherwise got broken

try using google forum search: quad current dumping sim
